WINDING-INDICATOR.

To all whom it may concern Be it known that I, Josnrrr MAZER, a citizen of the United States, and resident of McAlester, in the county of Pittsburg and State of Oklahoma, have, invented a new and useful Improvement in Winding-Indicators; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a winding indicator to be used in connection with watches, clocks, phonographs or other devices to which it may be found applicable, whereby it is possible by a dial located in view and an indicator hand to tell to what extent the main spring is wound, so that the observer may know not only when the spring is fully wound or when it has run down, but also the extent to which it is Wound at any particular moment and the time when it will require rewinding. I have already had several patents issued to me relating to these winding indicators, one of said patents being No. 790,508, granted May 23, 1905, and the purpose of my present invention is to improve such construction set forth in said patent in certain ways, so as to provide a simpler form of mechanism with fewer parts, while at the same time the parts are so arranged as to make them readily accessible in case of repair and so inclosed as to give a practically dust proof construction.

Other objects of my invention will appear as the invention is disclosed later in the specification, the above being merely a general statement of some of the main objects of said invention.

My invention comprises the features hereinafter set forth and claimed.

In the drawings Figure 1 is a face View of a watch showing my invention applied thereto; Fig. 2 is an enlarged diagrammatic view; Fig. 3 is an enlarged section on the line 38 Fig. 2.; Fig. 4 is an enlarged plan view of a portion of the rear face; Fig. 5 is a detail of one of the gears carrying the planetary gear; and Fig. 6 is a modified form of my invention.

In the drawing I have illustrated my invention as applied to the dial A of a suitable watch with the bottom plate B, which is provided with the recess C for the recep tion of the parts hereinafter set forth.

The main-spring barrel (1 has the pinion 7) formed integral therewith or attached thereto in any suitable manner, said pinion meshing with the gear-wheel d. The gear Specification of Letters Patent.

wheel (1 is mounted loosely on the bearin g of the double pinion g mounted on the sha t or pin 3 The pinion 9 extends up through an opening in said wheel 03. Below the bearin 9 IS a shoulder g which engages the whee d and holds said gear in place. The pin g has a journal or neck g which fits in a bearing in the plate B. Secured to the gearwheel (1 by the screw 6 is the double planeta-ry gear 6 provided with the teeth 6 and e. The teeth 6 of the planetary-gear e mesh with the teeth 9 on the pinion g. The gear-wheel c is mounted on the shaft 9 and said gear-wheel has the pinion f which meshes with the teeth 6 of the planetarygear 6. The gear-wheels d and c are dished or recessed so as to provide a space 0' between the same for the reception of the planetary-gear e, as well as the inner portion of the pinion g and the pinion f. The outer edges of the gear-wheels c and d are provided with the flanges 0 which bear against each other so that when the gearwheels 0 and d are arranged as shown in Fig. 3, a practically dust proof casing is provided for the parts contained within the space 0 inclosed by said wheels, while at the same time by said construction, I am enabled to make a more compact arrangement and thereby reduce the space required for the parts as more fully hereinafter set forth. The teeth 0 on the gear-wheel o mesh with the pinion l secured to the shaft 1 which is journaled in the plate B. At the upper end of the shaft Z is the gearwheel Z which meshes with the ratchetwheel k, which in turn meshes with the gearif wheel m. The gear-wheel m meshes with the gear-wheel n, loosely mounted on a screw n through which the shaft 0 passes which carries the indicator hand 1'. The gear-wheel n has the bevel gear n which is engaged by the bevel inion .s' on the winding shaft 8. Secure to the lower end of the shaft 0 is the gear-wheel i which meshes with the ear-wheel h. This gear-wheel i will be refiarred to in the claims as the indicator-hand wheel. This gear-wheel h in turn meshes with the teeth 9 of the pinion g. The plate J is secured to the watch-plate by the screws J and covers up the gearwheels i, h and 9 so that dust and dirt is excluded. I

The operation is as follows: Let us assume that thewatch is run down and that it is to be wound up. In this case the indicator hand 1" will be pointing toward the word wind on the dial of the indicator. By

turning the winding-shaft s, the gear-wheel" a is rotated and through it the gear-.

previous arrangen'ients which have given iree access to any dirt particles which may wheel m. Rotary motion is imparted to the ratchctwheel Z1 by gear-wheel. m and from the ratchet-wheel is to the gear-wheel Z. The pinion Z on the shaft l imparts rotary motion to the gear-wheel c, which in turn, through the pinion f imparts rotary motion to the planetary-gear e. The teeth e of the planetary-gear engage the teeth g of the pinion g. The teeth 51 of the pinion g meshing with the gear-wheel it drives said gearwheel and through it the gear-wheel 2' on the indicator shaft 0. In this manner the reverse movement is imparted to the indicator shaft 0. At the same time the wind ing of the watch is accomplished, the ratchet-wheel is being mounted on the barrel-arbor t which carries the main-spring barrel a.

when the watch is unwinding the power to operate the indicator-finger r co nesfrom the unwinding oi the main-spring barrel a, through the pinion r engaging the gearwheel (Z, said gear-wheel carrying the planetary-gear c which in turn meshes with double pinion g. The pinion g meshes with It which meshes with carrying an indicator hand.

By connecting tne gear-wheel (Z to the small pinion F1 instead of to the periphery of main-spring barrel a, I reduce the speed at the startinstead oi afterward reducing it by a train oi gears or wheels, and I am enabled to greatly reduce the space required and simplify the construction.

liLIlOtllGlf point of advantage of my con struction is that l have all the wheels which perform the actual reversing of the indicator-hand between the two wheels 0 and (Z, the one connecting to the main spring barrel and the other tothe ratchet wheel, whereby I am enabled to provide a practically dust proof arrangement and in addition tothat, save the space which would be necessary to allow for clearance where one wheel was mounted on top of the other, instead. of facing. each other, as they do in said patent. Furthermore, by making an extra large hole in the wheel cl'an d making the pinion g with the stud g? act as its own bearing, 1 put the watch together from the outside rather than from the inside, was formerly the case, and by mounting of the gear-wheel (Z on the pinion said gear-wheel acts as a cap to hold the wheels together. l urthermore, by having the opening in the wheel (Z large enough, the gear-wheel (Z, carrying the planet-gear may be lifted off the pinion, or the pinion lifted from it without removing the screw holding down theplanet-wheel.

Another important feature of my invention is that the whole indicating mechanism is placed within a recess within the plate which when covered by the cap J makes the whole arrangement dust-proof and unlikely to catch dirt, in direct contrast with be about.

In Fig. 6 I have illustrated a modified form oi? my invention in which the double pinion p is a deep spur-gear which forms a bearing for wheel u and the upper portion oi the teeth mesh with the planetary pinion c. The lower portion of the teeth mesh with the intermediate gear-wheel it connected up to the indicator hand by the gear-wheel 00. Furthermore, the edges or flanges, of wheels 14 and u overlap so that the wheel a also. forms a bearing for the wheelu in addition to the bearing formed by the teeth of the double pinion 2;.
